The TV mogul has sparked speculation that there could be a revamp to the judging panel in next year's series of the ITV talent show.

But former Mis-Teeq singer Alesha, who joined the ITV talent show in 2012 alongside Simon, Amanda Holden and David Walliams, told the Daily Star: "I really hope he doesn't leave. When Simon is on the panel people really want to impress him.

"They want to come along and get his approval. So it wouldn't be the same show without him," she added.

Meanwhile, David added fuel to the rumours when he wrote a tongue-in-cheek post on Twitter: " Hi @SimonCowell shame I will never see you again. Best of luck with everything. x"

The funnyman also posted a link to a story about Simon's possible exit from the show, followed by "YES...!"

Simon previously hinted he may make a tweak to the judges' line-up for the next series.

He said: "I'm possibly looking at a shake-up for next year. It's about having a conversation to see how much they want to be on the show. Are they still into the idea of finding a star? I never want a judge for hire. I want someone committed."

Millions of viewers watched operatic boyband Collabro as they were crowned the winners of the eighth series of Britain's Got Talent in a grand finale on June 7.
